For some reason it's stopped working, and when i try and connect it says my firewall may be blocking it from connecting to the internet. But as far as im aware nothing has changed in the settings.

I've had a look in the settings for the firewall but it says it should be ok. Tried reinstalling messenger, but to no avail. So.. any ideas?

its the firewall

Yes but from what i can see, there is nothing wrong with the firewall.

tis the firewall

pfft

try disabling your firewall, sign in and then undisable.

No offense, but that is just a brilliant, new word

Could probably have just said enable, but your new word works well. ta, i shall give it go.

Doesn't work
